Be it known that I, J OHN PELZER, acitiaen Y and closingv oftransoinsxorwindows which` are not usuallyeasy of'access,i and has forv its objects-First, to devise such mechanism as will be simple, chen-pand eficient and can 15 be .wholly concealed in the facingsof a door or in the walls of `a build-ing. Second, to devise mechanism for such purpose as will render it possible `to effect the accurate closure of the transomfat alltimes.: Third, to

Y devise such mechanism -as will make it easily `accessible at all times andwill not be liable to get outof repair or become inoperative at any time, as .isso often=the case with transoms made operative at. a point accessible to theuser, and will also make it possible to easily, quickly and completely remove the transom for the purpose-of cleaning, repairing, etc. Y jt Y fr My invention will be fully understood byv referring to the accompanying drawings, in which,V v

The .parts so far. described, except` the Afiat locking spring s, are disclosed in a copend. ing applicationvled by me in: the1U. SrPatlever havingv an enlarged'end for4 connecting4 10b i ent i(Diiiceon ,thebthj day vof,November,1912,f1ro i kand bearing Serial No. 7 29,663, and directed' to an improvement in mechanical moveclusive, 1 will describe the entire invention,`

as follows- 16 is an enlarged end of the lever 15 for a purpose to be hereinafterdescribed.v

17 represents the transom pivotally held by. my improved means in the upper portion of the door facing 18, see Fig. 4.

19, 19 represent two journal bearings secured to the opposite-inner yfaces of the door by screws20, 20. 21, 21 are journals or pivots sustained by the journal bearings 19, 19. The journal 21, seen in Figs. 1 and 3 and on the right in Fig. 4, differs from the other ournal 21 on the left in that it is provided with means for eifecting the angular adjustments of the transom, so that after it is put together it may be adjusted so as to accurately fit the opening in the frame in a vertical position when closed, andy to accom plish this I provide said journal with two oppositely disposed grooves 22, 22 (see Figs.

3 and 4) and arrange the journal itself tov accuratelyv fit the enlarged end 16. as shown in Fig. l, and l provide a key 23 with upturned ends (see Fig. 3) and the enlarged end 16 with two adjusting screws 24, 24, j

adapted to bear at their inner ends against Y the key 23l so that the angularlposition may e in vertical alinement when the transom is closed, as will be described later on.

25, 25 represent a pair of narrow sustaining plates each permanently secured by two screws 28, 28 in grooves g to the opposite ends of the transom, as shown in enlarged view Fig. 3. Each of these plates is forked at its upper end, as shown in Fig. 5, for the purpose of acting as a. journal bearing for the journals 21 and turned outward in opposite directions at its lower end, as shown by the numerals 26, Figs. 3, 5 and 7.

29, 29 are narrow sustaining plates similar to the plates 25 and secured thereto by` 1 is secured by screws to the inner casing of the door and i'n the manner shown in Fig. 4. The controlling pin y) is then inserted in the extendedk side 6 and the yvertical connecting link or rod 14 which is connected in turn to theshort connecting lever 15. The flat journal bearings 19 are then securedvby the screws 20 in the inner faces of the door. The Vsustainingk plates 25 are secured in the manner shown with their forked ends eX- tending upwardin the groove'g within the .opposite ends of the transom by screws 28,

asshown, the lower downward projections 30 having a bearing betweenv the outwardly. turned ends 26 of the,- plates 25. The short connecting lever 15 is connected to the journal 21j, the key 23 having iirst: been inserted, after which the transom is turned to proper position and adjustment effected byY the screws 24, 2.4 by4 adjustingV them against the key 23 and the faces/of one of the grooves The device is now ready for operation andany turn of they knob 13 in a given direction either opens or closes the transom a proportionate amount each semi-turn placing the teeth 10 of the head 9 in the position shown in Fig..2 by reason of they action of the strong :tlat spring ls ,thereby eiiectually locking it. It will thus be seen that with this mechanism the transom may always be operated in a given ydirection and that after the semi-revolution of the knob 13.

it assumes a definite locked position and that adjustment thereof may be eifected by varying the position of the adjusting screws 24 with relation to the key23.

1t will also be understoodthat the transom may be readily removed for the purpose of cleaning, or for inserting a new glass, if the same be broken, or for the purpose yof painting the frame thereof; or for repairs generally. Y

I do not limit my invention to the specic structural device herein shown and described as I believe it iis broadly new with me to provide a transom which automatically assumes a self-locking position for every portionof its movement. I believe it is also Vbroadly new with me to provide a transom operating mechanism which permits of the ready removal of the transom without materially disturbing the operative parts thereof and my claims are generic in these particulars.

l make no claim in the present application to a mechanical movement acting upon the principle disclosed in the mechanism herein described, such mechanical movement being described and claimed in a copending 'application above referred to and bearing Se-l rial No. 729,663. l Y

Having thus described my invention what 1 claim and desire to secure byv Letters Patent ofthe United States is-v j 1. A transom operating device embracing rack and pinion mechanism 'for tothe of'ia. door` vand provided i' with vadjusting transom motion in opposite directions,V andy simultaneously automatically locking it twice in each revolution of the pinion in any position as it is advanced; in combination with means for adjusting the angular position of the transom.

2. A transom operating device embracing -rack and pinion mechanism for giving toit motion in opposite directions, the transom l lbeing detachably journaled in the window7 VCopies of this patent may be obtainedtor screws connected with one of the pivots and Y angular position: i
